I Have Acne Pit Scarring. Will the Dermapen Work?

I have acne pit scarring on both my cheeks - I am a bit reluctant to use lasers and so I looked into dermarollers but I read a few reviewes about the needles bending on the dermaroller which can cause more damage. I have also heard that the results are not permanent. I have read some good reviews about the dermapen and I have booked a consultation at a private clinic. It's expensive so I'm wondering whether I will just be wasting my money?!
